Ukrainian drones struck a multi-story building in Lipetsk and caused multiple explosions around the city, according to Ukrainian monitoring channels. Eyewitness footage from the scene appears to show low-flying Ukrainian drones and fires lighting up the night sky.
Ukrainian forces struck energy infrastructure in the city of Chystiakove in Donetsk Oblast, and blackouts were reported in Crimea amid drone fire, monitoring channels reported late on Oct. 20.
Among the drones it produces are the Sarych, which uses video and thermal imaging equipment for surveillance, and the Klin, a loitering munition designed to strike targets, according to Ukraine's military intelligence agency.
Russia's Federal Air Transport Agency announced restrictions at three of Moscow's four major airports, while the Transportation Ministry said the region's aviation operations were under "special monitoring."
Ukrainian activist and volunteer Serhii Sternenko claimed the facility was the Surgut Condensate Stabilization Plant, which processes gas condensate and produces petroleum products.
'Striking such systems reduces the enemy's ability to monitor airspace and detect aerial assets in time. The estimated cost of the radar station is about US $100 million,' the General Staff said.
According to monitoring channels ExileNova+ and SuperNova+, Russian technology giant Yandex's data center in Vladimir Oblast, around 500 kilometers (310 miles) from the Ukrainian border, was targeted in the overnight operation.
Ukrainian defense company Fire Point commented in a social media post on Wednesday morning, saying 'You didn’t think it would stop with just Yandex, did you?'
